    Ok....just curious. I do know that the crf kicker is much stronger than the stock one. However you also then geared first gear down much further. I think H models are 2.692 first gear where AHP is 3.182

    CT70H
    2.692
    1.823
    1.300
    0.958

    AHP
    3.182
    1.706
    1.238
    0.958

    The bike looks great though! The Superhead 108 will get you to about 70mph. How are you geared? I'd hazzard you should be about 15/16-35 to get the most from that motor.

    Yes, geared 16-35. I have been talking with a well know CT engine builder along the way who has been giving me a bunch of advice, didn't want to guess as I build the engine.

    The HK1 Stroker build is complete! I was able to take a few photos between rain storms today as well as get a brief video of the initial start up.

    Rode the 108 with V2 head and 26mm carb back to back with my 88 with race head and 20mm carb. Both are a kick in the A$$ to ride but the stroker is something special. The 1down 4 up manual is a blast and the thing pulls like crazy. I was doing 50mph and it had plenty more to give!
